Improves Handling. Lower your S550 Mustang's center of gravity by installing a set of Steeda Sport Linear Rate Springs, which will reduce squat during acceleration, body roll in the corners and excessive nose-dive under hard braking. Steeda Sport Springs are great for daily driving, street and even occasional track use.

Linear Rate. Using a Linear Spring, also known as Standard Rate Spring, the set of Steeda Sport Springs not only enhances the handling performance of your S550 Mustang, but they also improve its overall appearance by lowering the ride height approximately 1.0" in the front and 1.0" in the rear to eliminate that ugly "4x4" tire to fender gap, for a more aggressive street stance.

Clears Stock and Aftermarket Wheels & Tires. These lowering springs were engineered to be compatible with your stock size wheels and tires, as well as AmericanMuscle's pre-configured wheel and tire combo kits (specific to your generation), to assure proper clearance with no rubbing issues.

Application. This set of four Steeda Sport Linear Lowering Springs are specifically designed for use on the 2015-2019 GT and V6 Mustang Fastback and Convertible models. Does not fit EcoBoost Mustangs.

Technical Note. The Springs are not compatible on vehicles equipped with the MagneRide Suspension.

The steeda linear springs are a quality product that delivers decent performance and a mild stance.... If you are looking for an aggresive stance and or ride these are not the springs for you! 2016 mustang gt pp

With a set of these lowering springs, not only does the car set flush now, it also performs a lot better. The car has reduced nose dive and squat. I put these on before I got aftermarket wheels and the stock 18s just did not look right so I got some 20 inch wheels. They sit perfect with no rub!

I purchased these after my friend had been through three different sets of springs. He finally bought these and highly recommended them. So I bit the bullet and spent what seems like a lot for springs. All I can say is WOW! The linear spring rate makes them predictable and easy to control around turns. The Look is fantastic and it still has a comfortable ride. Slightly firmer ride but significantly better handling!!! Never owned a mustang that can handle like this!!!
